Is a crisp the same as potato chip? If so eat it. The green has something to do with something that starts with a G that I learned in Bio-101 a couple of years ago. Sorry for the long-winded technical answer.

As you know, crisps are made from potatoes.

Are green potatoes safe to eat?

No, the green section may contain naturally occurring poisons called alkaloids. Potato varieties are not released in Australia if they exceed the maximum level set for alkaloids. This rule minimises the chances of severe poisoning where green potatoes are accidentally eaten.

So, no it's not really safe to eat them as they may contain poisons.

Quoting GVBIG (Reply 5):So, no it's not really safe to eat them as they may contain poisons.

I think alkaloids are the least of your worries. Any snack item where the Roast Beef flavour is suitable for vegatarians, and the cheese 'n onion flavour isn't, has some serious additive issues, and is best avoided.

Quoting Cornish (Reply 7):More importantly - should you have been eating Ready Salted when there are far more delicious flavours to be eaten

As discussed via e-mail Mr Cornish - I went for the safe bet as the green ones (which SHOULD be Cheese & Onion) and Salt 'n' Vinegar (which SHOULD be blue) are opposite in Walker's packets (WHY WHY WHY). Early on a Monday morning I went for the red as I don't think I could've done C&O before my first pint of meths....

See I would recommend a boycott of Walkers, but as they seemingly control the entire UK crisp industry now I'd be cutting off my nose to spite my face. After all I'd have t stop eating Pickled Onion Monster Munch and I don't think I have that much willpower

Just when I thought I could see light at the end of the tunnel, it was some B*****d with a torch bringing me more work

That goes for Thai Green curry flavoured, basalmic vinegar and sea salt (call it salt and vinegar for god's sake!), aubergine and yoghurt or whatever other god awful ridiculous flvaour they think of next.

For you Cornish backward thinking people who still think foil bags are a new invention then I agree that these are poncey crisps, but for us sophisticated Devon-type people these are everyday run-of-the-mill crisps.
